Which principle best explains the need for explicit lines of authority and defined duties?

• A. Clear lines of authority and distinct statements of duties
• B. Unity of command
• C. Liberal delegation
• D. Informal authority by personality

Answer: (A)

Explicit lines of authority and defined duties establish a formal structure that makes who can make which decisions and who is responsible for what work clear to everyone. This clarity is essential for accountability, coordination, and efficiency. When roles and powers are clearly set out, tasks don’t drift between people, decisions aren’t made by accident at the wrong level, and performance can be measured against well-defined expectations. It also makes supervision and delegation straightforward, since it’s obvious who approves actions and who carries them out.

Other approaches lack this formal clarity. Relying on broad delegation spreads decision rights without clear boundaries, leading to confusion and inconsistency. Relying on informal authority by personality depends on personal influence rather than an official structure, which can vary and undermine fairness and predictability. Unity of command focuses on reporting to a single supervisor, which helps supervision but doesn’t by itself define the exact duties and authorities needed to prevent overlaps or gaps in responsibilities.
